[R-pkg-devel] CXX14 not defined on Windows

[Guido Kraemer]

I had some success using RTools40 and the corresponding R testing 
version. I had to do a lot of MSYS shenanigans and couldn't get static 
compilation to work, but the binary package seems to work just fine in R 
3.6.2.

It makes me very happy to see that R will get an updated toolchain and a 
proper MSYS environment with a package manager! Is there a due date for 
R 4.0.0?
